Description
Technical field
The invention provides novel dry powdered colorant and distribute filling material (dry powder colorant dispensingcharges, " DPCDC "), it comprises coloured powdery carrier (Powdered Colored Carrier, " PCC ") system or micro-dimension colour batch mixture (micro-size color concentrate mixture, " MCCM ") system, described dry powdered colorant distributes the filling material to be used for preparing painted thermoplastic article by the various technology that comprise injection molding.The present invention also provides the novel method that uses DPCDC of the present invention to prepare the colored thermoplastic goods.
Background technology
By make such as injection molding method the colored thermoplastic goods during, different with colored surface only is can add tinting material to carry out painted to whole goods.In order to realize this, with dry colorant (by, for example pigment dyestuff, mineral dye, dyestuff or colour batch) or liquid colourant be added in the plastics, plastic pellet as part allotment, as additive tinting material pill, as liquid, plastics enter injecting unit before add immediately or add simultaneously.
Consider the internal performance of the pigment that in this method, uses and their target capabilities functions in the main body plastic material, at first must carefully weigh and mix these pigment.Blend pigment in mixing tank has obtained particle by machinery or chemical technology and has reduced, and removes moisture.Usually, with the tinting material and plastic pellet twice of the blend at least of allotment.Then, the coloured plastics material material is carried out heat/process of smelting, further distribute during this period and be scattered here and there toner.As the net result of this method, plastics are molded as required spatial form.
Pigment and dyestuff are two kinds of main plastic colorants that are used to prepare the colored thermoplastic goods.Comprise the composition that dissolves in thermoplastics as the example of thermoplasticity tinting material, described composition comprises the chromophoric group of following material: quinacridone, anthraquinone, two perinaphthenes, indigo, quinophthalone (quinophthalone), indanthrone, iso-dihydro-indole, isoindoline, dioxazine, azo, phthalocyanine or diketopyrrolopyrroles.These dyestuffs produce brighter and denseer color than pigment, can be used in the color of enhancing based on pigment, and can be used in transparent plastics are painted.Yet the limitation of dyestuff comprises the following fact: they have poor UV stability and thermal characteristics usually, and bleeding and separating out in polyolefine and engineering resin may respond badly, transparent in high temperature process, and does not have the color change of pigment.
Pigment is the organic or inorganic subparticle, and it has about 20 microns sizes to about 0.01 micrometer range, and can disperse and be suspended in Plastic Resin or the mixing material.The example of pigment dyestuff comprises the composition that comprises phthalocyanine, quinacridone and isoindoline.Mineral dye comprises and comprises titanium dioxide, ferric oxide, ultramarine and and the composition of some heavy metals.Pigment is used in and produces opaque and translucent effect in the plastics; Normally cost is effective; Can provide the dispersing property of enhanced UV stability, thermotolerance and increase, the environmental friendliness of increase; And be widely used in black or white use in and in colored the application.
Yet the limitation of pigment comprises the following fact: they are insoluble in the plastics usually, and the bad dispersibility in plastics; When comprising heavy metal, there is environmental problem; And under some processing conditionss, confirm unstable.In order to help colo(u)rant dispersion to be dispersed throughout in the molten plastic, with the Plastic Resin blended during, for example dispersion agent such as polyethylene wax adds in the pigment usually.Dispersion agent is fusion at low temperatures, and plays the effect of lubricant, thereby helps between articles colored fusion of preparation and hybrid technique colo(u)rant dispersion to be dispersed throughout in the plastics.
And dyestuff and pigment are used to generate the tinting material of four kinds of main types, and these tinting materials are used to prepare the colored thermoplastic goods.These tinting materials are dry colorants, are made of powder material, and supply with the packing (pre-measured package) of premeasuring usually.Dry colorant is economical, and preparation is suitable for small serial production easily, there be not " Minimum Order Quantity (" MOQ ") ", can be used in short and urgent operation, be fit to be used for rotational molding, and can in short delivery cycle, supply by numerous suppliers with polyethylene.Yet when with resin premixed fashionable, dry colorant needs a large amount of processing, produces dust pollution, and this has influenced Working environment and processing units unfriendly.
Liquid colourant is made of fluent material, and fluent material comprises pigment or the dyestuff with different viscosity.Liquid colourant uses easily, is that cost is effective for long-term and continuous operation, and is compatible with multiple plastics, presents good dispersiveness usually, can be changed fast, and produces minimum spillage of material.Yet, the delivery cycle of using liquid colourant to rectificate; Limited material choice; Be subjected to the restriction of preformulation tinting material; Only can move use continuously; With regard to batch production or low capacity production is inflexible; Expensive relatively have MOQ with inventory value with for various colors.
Usually, the dry colorant that uses in the thermoplastic moulded technology is about 0.1% Plastic Resin to about 1% tinting material/unit weight with respect to the weight percent of Plastic Resin.Yet per injection is difficult to a spot of like this fines dry colorant distribution becoming liquid colourant.Common practice is that dry colorant is mixed with Plastic Resin and small amount of mineral oil, makes the tinting material powder adhere to (this is commonly referred to " coloring process ") on the resin pellet surface.Coloring process is in the processing of material and mix and need a large amount of operations aspect the machine barrel cleaning, and during this technology, Plastic Resin contacts with air, may absorb moisture and contaminated.Bucket type drying (hopper drying) also causes dry colorant is blown in the environment.
Injection moulding uses conventional colour batch, with the resin pellet pre-mixing, be dispensed in the mixed melting barrel unit (mix and melting barrel unit), injection moulding still suffers following disadvantage: dumb (colour batch must customize), more expensive, MOQ (this is bad for little batch production), longer delivery cycle, and practicality is limited to general plastics, for example ABS (acronitrile-butadiene-styrene), PVC (polyvinyl chloride), PE (polyethylene), rather than engineering plastics, for example nylon and POM (polyoxymethylene).Conventional colour batch is the material that is dispersed in the resin of preparing with the use of independent resin series.Conventional colour batch obtains with pill, pearl, cubes (cubes), thin slice (wafer) and microballon form; There is not dust; Flow easily; And measure easily.Yet, conventional colour batch is developed than the cost of alternate tinting material longer delivery cycle, preparation in advance, be fit to operation rather than little periodic running continuously, not as pigment flexible, only can be from the limited supplier acquisition of originating, do very well than liquid colourant, but, have high inventory value, and various colors are had MOQ not as dry colorant.
When the resin of precolor arrives the plastic working machine, be colored certain specification, and the facility of instant material, superior dispersiveness are provided, do not had contamination by dust.Yet the resin of precolor is inflexible relatively, and the acquisition of only originating from the supplier of limited quantity has big MOQ to various colors, and be not suitable for all plastics the delivery cycle that will rectificate under the low consumption situation.
United States Patent (USP) 5,462,709 described a kind of at forcing machine to polymethacrylate or poly-glutarimide method of colouring, described method comprises: directly the molten thermoplastic plastics of the transmission of the converging operation from the forcing machine mixing zone mix with the dispersion of at least a pigment, dyestuff or the tinting material that are arranged in the suitable transparent carrier, blended colored thermoplastic plastics are sent to extrude district or injection molding district then.
United States Patent (USP) 5,919,530 have described following method, and this method comprises: the thermoplastic resin body that is in first temperature is provided; At least a portion to thermoplastic resin body applies the thermoplastic coating composition, described thermoplastic coating composition comprises binder component and polymeric component, described binder component comprises the pigment based on about 3% to 8% weight of described custom heat plastic resin weight, wherein said coating composition has the melt-processed scope, and wherein said further first temperature is higher than the beginning temperature of coating composition melt-processed scope; The thermoplastic resin that cooling applies generates the thermoplastic resin that customizes with solidified coating.
Yet, technology in the above-mentioned document does not satisfy the needs of improved technology, described improved technology prepares painted plastic components by the various technology that comprise injection molding, described improved technology has following characteristics: the materials processing amount of minimizing, natural pigmentary resin is fed directly in the mould machine, hopper dry resin pill and do not have pigment only, tinting material directly is dispensed in the mixed melting barrel unit as liquid colourant or colour batch, has handiness, and be equivalent to the economy that existing dry colorant technology provides, do not have MOQ short delivery cycle, and be equivalent to the color diversity that existing dry colorant technology provides.
